5x – 2x + 7 – x = ?x + ?

Mathematics
1 answer:
fomenos2 years ago
8 0

Step-by-step explanation:

5x – 2x + 7 – x = ?x + ?

I need the answer for "no solution" and "infinite solutions".

NO SOLUTION:

no solution because any value you give to x is not solvable, it remains +7

5x – 2x + 7 – x = ?x + ?

2x = 2x + 7

INFINITE SOLUTION

infinite solutions because any value you give to x is solvable

5x – 2x + 7 – x = ?x + ?

5x – 2x + 7 – x = 2x + 7

2x + 7 = 2x + 7

A tangent and a secant x = ?
guajiro [1.7K]

x = 45°

Solution:

Given data:

Measure of larger arc = 152°

Measure of smaller arc = 62°

<em>If a tangent and a secant intersect at the exterior of a circle then the measure of angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>

$\Rightarrow  x = \frac{1}{2}(\text{ larger arc }- \text{smaller arc} )

$\Rightarrow  x = \frac{1}{2}(152^\circ-62^\circ)

$\Rightarrow  x = \frac{1}{2}(90^\circ)

⇒ x = 45°

The value of x is 45°.

An alpine area of a national park near a trail is normally covered by plants, but much of the area is now bare soil. Park ranger
Ira Lisetskai [31]

Answer:

The correct option is;

comparing plant survivorship in areas where hikers stay on the trail with plants where hikers leave the trail

Step-by-step explanation:

The hypothesis that the area formerly covered by known plants which is now bare soil due to trampling in the alpine areas by hikers can be tested by means of comparing the areas where during the cause of their visit, the hikers remain on the trail as they move within the park to other portion of the park where it is known that there are either very few or no hiker remain on the trail. The outcome will determine if the cause of the appearance of bare soil is due to the transit and trampling by hikers.

using the midpoint formula, solve for the midpoint of the segment with these pairs of endpoints (-11,30) and (-26,-2)​
REY [17]

Answer:

Midpoint is (\frac{-37 }{2},  14)

Step-by-step explanation:

Midpoint = (\frac{x_{1} + x_{2} }{2}, \frac{y_{1} + y_{2} }{2})

              = (\frac{-11 -26}{2}, \frac{30 - 2 }{2})

              =  (\frac{-37 }{2}, \frac{28 }{2})

              =  (\frac{-37 }{2},  14)

Midpoint is (-37/2, 14)
